Specification of Letters Patent.

-To'aZZ whom t may concern: i Be it known'that I', JOHANN F. T. Bnnonin: a citizen ofthe United States of Amer1ca,g residing at Mount "Clemens, 1n the countyy of Macomb' and` State of Michigan, have invented certain new and useful Improvements in Road-Scrapers, of,l which the following is a s'pecication, reference being@ had Atherein to the accompanying drawings, This invention relates to improvements 1nI road scrapers especially 'adapted for scrap-.- ing and leveling'the surface ofthe road and; its object is to provide a construction whichF is such that vthe rough and uneven surface of the road is cut away-by a' scraper and the dirt thus scraped and loosened from thej surface is again distributed over the same surface and deposited in the depressions thus leaving a smooth even surface to the road-bed in going over the road but once with a scraper embodying this invention.

To this end theinvention` consists in the matters hereinafter set forth and more particularly pointed out in the claims reference bein had to the accompanying drawing in whic Fifrure 1 is a plan view` of a device embodying the invention; Fig. 2 a longitudinal section thereof on the line -m of Fig. 1; Y

and Fig. 3 is a transverse section on the line y-y of Fig. l.

As shown in the drawing two runners 10, 10 are connected in spaced relation by transverse rods 11 and bracemembers 12 and 13. These runners are each preferably formed of planking without openings from end to end thereof so that the dirt which is scraped from the surface of the road-bed by the scraper 14 will be prevented from escaping laterally froml between thesevertical walls formed by the runners. The scraper 14 consists of a blade mounted in guides 15 upon the inner sides of the runners and extending diagonally across between therunners. This blade may be of any desired construction and form and is adjusted vertically in its guides by any suitable means such as screw-threaded rods 16 having hand wheels 17 upon their upper ends and en- Y mitted when it passes along the inclined or diagonal side of the blade .to the yrearmost end 'the-reef, to pass through said opening 2O to the rea-r side of the blade. 'A leveling bar 21 located rearwardly of the. scraper blade, extends diagonally across between the runners in an opposite diagonal direction from that in which the blade extends.A The lower edge of this bar is even with the lower edges of the runners and thus the dirt which passes through the opening 20 in the blade comes into contactf'with the forward side of the leveling bar and is distributed by Said' bar, because of its inclination, across the surface of the road between the runnersa-nd fills the depressions inthe road surfacefgpAs the bar 21 extends across between the run-l ners with its lower edge. in the plane ofthe lower edges of the runners, there is no chance for the loose dirt to escape from be"- tween the runners except by dropping into. the depressions in the road surface and passing beneath the leveling bar.

In this construction all of the dirt which is scraped from the surface by the scraper' blade is held by the runners fr'om escaping laterally and is then distributed overthe surfaces between the runners to fill in the depression in the road surface by the levelingbar. There is therefore no ridge 'of dirt Patented Sept. 3, '1912. .applicationl ined April 1-5', 1912. seriai'm. 690,693.

left at one side of the path of the scraper as is usually the case with road Scrapers and therefore the surface passed over by this road scraping and leveling machine will be leveled by one passage of the machine over the surface while with a machine of the usual type it is required to be passed over the surface-several times in order to level olf the ridge ,ofdi'rt which is -left'at one side of the scraper.

Obviously, changes in the construction "and arrangement of parts may be made without-departing from the spirit of my invention and I therefore do not wish to limit myself to the particular form and construction shown.

Having thus fully described my invention what 1 claim is Y 1. In a device of the character described, the combination of runners spaced apart and forming-side walls to revent the escape of material laterally from between said runners, a scraper blade extending diagonally across between said runners and provided with an opening near its rearmost end ad= jacent to' one of the runners to permit ma'- V"and forming side walls the plane of l 2f@ ners, said leveling member being located terial to pass therethrough and a leveling member extending across between said runners rearwardly of said blade and/in a diagonal direction opposite to that of the` blade. 2. In a device of the character described, the combination of runners spaced apart to prevent the lat eral escape of material from between said runners, a scraper blade extending diagonally across between said runners and hav ing a portion cut away from its lower edge adjacent to it-srearmost end forming an opening adjacent to one of the runners for the passage of material therethrough, means for adjusting the blade vertically, and a leveling member extending between said runners in a diagonal direction opposite to that of the blade with its lower edge lin the lower edges of the runrearwardly of said blade with its forward l @epics of this patent may be obtained for ve cents each,

end adjacent to the end of the blade having the opening therein.

3. In a device of the character described,

ytitle combination of runners having lower edges to engage the surface of afioad, and

forming side walls to prevent the lateral escape of dirt from between said runners, braces for spacing the on the inner sides of said runners, azblade runners apart, guides enga g said guides at its ends and extendbetween the runners,

for ralsing and lowering said blade in its and a leveling member extending between said runners in a diagonal direction opposite to that of the blade rearwardly of said blade with its lower edge in thejplane of the lower edges of the runners and its foremost end adjacent to the rearmost end of the blad In testimony whereof I alix in presence of two witnesses.
